“A boozy comedy club is a much easier situation to deal with. Most of the time it works, otherwise one would have to consider giving it up and in most situations they have paid to be there and have faith in you to entertain them.

“Contrast that, if you will, with a group of 30 or so hormonal adolescents who are see the words supply teacher and to them it reads free reign.”

Kevin brings his latest show, Not Appropriate, to the Ipswich Regent on February 6.

The most overused term of disapproval in the teacher’s canon, he explores his former life as a teacher.

“I was full-time for four years teaching RE at Secondary level, a tougher gig than comedy in my estimation and not high on the list of most student priorities. Despite that, I taught it as a humanities subject - six world religions, moral, spiritual and philosophical issues.”

He remembers teaching a module on Jesus and the Easter story to a bunch of largely uninterested Year nine students and in order to engage them with the story he used the film Jesus of Nazareth starring Robert Powell.

“I showed them an excerpt each lesson as the story progressed as a means of discussing the ideas contained in the Gospels. As most people are aware, after being interrogated by Pilate, Jesus is taken away to be whipped by Roman soldiers. It was at this point that one of the students turned to me and asked ‘sir, do they kill him?’ I decided not to spoil the ending.”

Kevin did another four years as a supply teacher in order to facilitate the move into comedy, which also presents certain challenges.

He’s sure he must’ve uttered the phase Not Appropriate at some point or other; it tends to be used as a response to bad or suggestive language and behaviour.

“I use it as the title of the show because it encapsulates a lot of things as a teacher I would have liked to have said but obviously, one is bound - rightly so - by certain ethical standards and expectations. It’s the sort of stuff one might say on a car journey back from work or a boozy staff night out.”

More importantly, did a teacher ever say it to him when he was a student?

“I grew up at a time when teachers were much more direct and told you pretty much what they thought of you. Being called a moron or some such was commonplace.”
